What applies for products with the WEEE symbol?

In accordance with the WEEE (Waste of Electrical and Electronic Equipment) Directive, when products are no longer used
they must either be taken separately to a designated collection place and not left among unsorted
waste or be returned to Calectro for recycling. Calectro handles discarded products
in an environmentally responsible manner. The products are sorted and recycled as far as possible. Remaining
materials are sent for destruction.


How can you test that the control unit for the smoke detector is working?

The easiest way to test that the control unit is working is to remove the smoke detector loop from the control unit and instead to connect the termination resistor to the same terminals. The termination resistor is usually connected to the final smoke detector in the loop. If there is only one smoke detector in the loop, the termination resistor will be there. You do not, of course, have to locate the system’s termination resistor – you can use one of your own for this test.
PLEASE NOTE! Make sure that the test produces the correct resistance value. See the list below:
